Self-identified Teslaholic

Not sure if anyone else is experiencing this, but for the last couple of days, when I browse the forums on a mobile device, my browser occasionally gets hijacked by a spam/scam ad that redirects me to a third-party web page which tells me I've won something. (See examples below.) Even worse, this page is somehow able to play a looping sound file that proclaims "Congratulations! Congratulations! Congratulations!" over my phone's speaker in a creepy synthesized voice.

These ads tend to appear in clusters, so if I run into one, the odds of me running into another one on my next page load are also high.

I'm guessing one of the site's ad networks is selling to a bad actor or two, and I'm not sure if there's any action to be taken here by the M3OC site admins... but I just wanted to raise awareness of this disruptive issue in case there is.
